SPECIFICATION forming part of Letters Patent No. 351,095, dated October 19, 1886.

Application filed March 26, 1886.

To @ZZ whom, t may concern:

Beit known that I, WALTER ALnoN CLARK, of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Automatic Vheel-Retaining Attachment, of which the following is a full, clear, and exact description.

My invention relates to the construction of a cheap, efficient, and durable device, whereby vehicle-wheels may be secured to their axles, the apparatus being so arranged that the wheel may be removed by imparting a simple turn to the hub-cap, which, however, will be returned to its normal position by the action of a spring, so that when the hub is slid upon the axle the parts will be in position to permit the automatic action of the retaining device, as will be hereinafter more fully explained.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a centra-1 sectional View of my improved wheel-retaining attachment, certain portions of the clamping-box being broken away to disclose the arrangement of the guiding-pin. Fig. 2 is a similar View eta modified construction. Fig. 3 is adetail view illustrating the construction of the hub-cap. Fig. 4 is a detail view illustrating the construction of the sliding clamping-box. Fig. 5 is a sectional view taken on line a' r of Fig. l. Fig. 6 is a detail sectional view taken on line y y of Fig. 3, and Fig. 7 is a detail sectional view taken on line .z z of Fig. i.

In constructing such an attachment as is illustrated in the drawings above referred to, the end of the axle A is slotted, and in the slot c so formed there is arranged a double-armed spring catch or plate, B, that is held to position by a pin, b, the catch C at the end ofthe spring arms c c being arranged beyond the extreme end of the axle, and the outer faces of said catches being inclined or beveled, as clearly shown in the drawings. In connection with the axle, arranged as described, and a wheel-hub, D, recessed in the usual manner, I employ a hub-cap, E, the inwardly-projecting flange c of which fitsloosely in the recess of the hub, said cap being formed with slotsff, arranged upon opposite sides of the flange and at right angles to the axis of the cap.

Serial No. 196,663. (No model.)

The cap E is provided with an inwardlyprojecting pin, h, which rides in a longitudinal groove, k, formed in a sliding clampingsleeve, F, that is loosely fitted Within the cap E, and this sleeve F is also formed with two diagonal slots, g, as best shown in Figs. 4t and 7, the several parts being held together and being secured to the hub D by means of a bolt or screw, H, which passes through the slots f f of the cap E and the slots g g of the sleeve F. A spring, t, isixed to the inner face of the cap E and also to the bolt o r screw H.

It will be noticed that there is an annular shoulder, n, formed in the hub D, just inside of the flange e, and when the hub is forced to the position shown in. Fig. l the catches C C will spring out and will be brought into engagement with this shoulder, thus preventing the withdrawal of the hub, but if it is desired to remove the wheel from the axle, the cap E is firmly grasped and slightly turned to the right, the wheel being held stationary at this time. New, this turning of the cap E will cause the sleeve F to advance, and as the sleeve advances it will strike the iiaring beveled faces of the catch-teeth C and move said teeth toward each other against the tension of their springs c, the motion being continued until the teeth are freed from engagement with the shoulders n, after which the hub and the wheel which it carries may be slid off the axle. In moving the cap E to the right the spring t' is necessarily subjected to a high torsional strain, and when the cap is released it will be returned toits normal position. In certain cases I prefer to employ a circular Wear plate or Washer, O, arranged as clearly shown in Fig. 2, thus relieving the shoulder n from wear.

New, although I have described and illustrated a specitic arrangement of parts, I desire it to be distinctly understood that I do not limit myself to the precise construction shown, as many and various modifications of such construction could be made without departing from the spirit of my invention.

The facility and ease with which the wheels may be disconnected and removed from their axles for the purpose of lubricating the axles, or for any other purpose, will be readily appreciated; and it will also be appreciated that with the construction shown there will be lit- IOO tle r no liability of the axles being injured yby grit, as the cap E effectually closes the -tially as described.

2. The combination,with an aXle, of a plate secured Within a slot formed at the end of the axle, and provided with spring-arms carry-ing catches formed With inclined or beveled faces, a hub-cap formed with transverse slots, and an inwardly-extending pin, a clamping-sleeve formed with diagonal slots, and a longitudinal slot in which the inwardly-projecting pin of the cap iits,a nd a bolt or screw passing through the transverse slots of the cap and the diagonal slots of the clamping-sleeve, substantially as described.

3. The eombinatiomwith an axle, of a plate secured Within a slot formed in the end of tlie axle, and provided with spring-arms carrying catches formed with inclined or beveled faces, a hub-cap formed with transverse slots, and an inwardly-extending pin, a clamping-sleeve formed with diagonal slots, and a longitudinal slot in which the inwardly-projecting pin of the cap fits, a bolt or screw passing through the transverse slots of the cap and the diagonal slots of the sleeve, and aspring secured Vto the cap, and the retaining bolt or screw, substantially as described;
